ABSTRACT:
A mechanism 10 for diverting the flow in a wind tunnel from the wing 20 of a model being tested therein. The wing 20 is mounted on the wall 30 of a tunnel. A diverter plate 11 is pivotally mounted on the tunnel wall 30 ahead of the model. An actuator 18 fixed to the tunnel is pivotally connected to the diverter plate 11, by plunger 15. When the model is about to become unstable during the test the actuator 18 moves the diverter plate from the tunnel wall to divert flow about the wing and change the effective sweep angle thereof maintaining stable model conditions. The diverter plate is then retracted to enable normal flow.
